Over the 10 years since we first launched the Prius in 1997, the fuel efficiency
of all Toyota vehicles sold in Japan has improved by an average of
approximately 28%. This is the result of improved fuel efficiency in both
gasoline and diesel vehicles, and increased hybridization.
Toyota Hybrid Technologies
Since fossil fuels are finite resources, we continue to develop technologies
that enable vehicles to use energy sources other than petroleum. Although
the situation of these energy sources differs depending on the country and
region, we believe that the primary sources of sustainable energy are biofuels,
electricity, and hydrogen.
Approach to Diversification of Energy Sources
Corolla Flex
Toyota’s core technology, its hybrid
system, contributes to everything from
cleaner emissions and lower CO2
emissions to increased fuel efficiency.
As such, we are implementing it in an
expanded range of vehicles. In April 2008,
cumulative global Prius sales reached one
million. In June 2008, cumulative global
hybrid sales reached 1.5 million. We are
targeting one million hybrid vehicle sales
per year by the earliest possible time in
the 2010s. Achieving this goal requires a
drastic improvement in hybrid system
performance and fuel efficiency. We will
continue to develop high-performance
electric motors, inverters, batteries, and
other devices while working on ways to
reduce the weight, size, and cost. Our
current goal is to develop a hybrid system
that is one quarter the size, weight, and
the cost of the original Prius.
Hybrid Vehicles
Since 2006, Toyota has worked to ensure
that all of its models are compatible with
E10 fuel (gasoline with 10% ethanol).
Furthermore, we have introduced an E100
(100% ethanol) compatible Corolla Flex
in 2007, in Brazil, where bioethanol has
become a mainstream fuel. Also in 2008,
in Thailand we introduced a Corolla and
three other models that are compatible
with E20 fuel (20% ethanol). We also plan
to offer E85 (85% ethanol) compatible
Tundra FFVs and Sequoia FFVs in North
America, and are working toward the
introduction of other FFVs with
specifications that satisfy specific regional
requirements.
* FFV: A vehicle capable of running on fuels that
consist of any percentage of ethanol mixed
with gasoline or on ethanol alone.
